实体类
[code="java"]
@Entity
public class Category {
private int id;
private String name;
@Id
@GeneratedValue
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
[/code]
Dao层：
[code="java"]
@Component("categoryDao")
public class CategoryDaoImpl implements CategoryDao {
private HibernateTemplate hibernateTemplate;
public void save(Category o) {
hibernateTemplate.save(0);
}
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
@Resource
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
}
[/code]
通过Service 层测试：
[code="java"]
@Test
public void testAdd() {
Category category = new Category();
category.setName("c2");
categoryService.add(category);
}
[/code]
异常：
[code="java"]
org.springframework.orm.hibernate3.HibernateSystemException: Unknown entity: java.lang.Integer; nested exception is org.hibernate.MappingException: Unknown entity: java.lang.Integer
[/code]
网上查了很久，没结果，郁闷
